Gay- Lussacs law states that the pressure of a gas is directly proportional to temperature for a fixed amount of gas at constant volume.
therefore P/T = k
where P - pressure , T - temperature and k - constant 
 \frac{P1}{T1} =  \frac{P2}{T2}

parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - temperature in kelvin - 110 °C + 273 = 383 K
T2 - 65.0 °C + 273 = 338 K
substituting these values in the equation 

 \frac{22.5 psi}{383 K} =  \frac{P}{338K}
P = 19.9 psi 
new pressure is 19.9 psi

What temperature does blood boil at (in Celsius Kelvin and Fahrenheit)
Solution 1
where temperature is measured in Kelvin (Kelvin = Celsius + 273.15). For example, 1L of blood at 1 ATM boils at 373.15 Kelvin. If you doubled the atmospheric pressure, the blood would boil at 746.3 Kelvin, or 473.15 Celsius. Blood boils at approximately the same temperature as water, around 100 degrees centigrade.
Which would show an example of how physical changes are reversible ?
Solution 1


Non-destructive physical changes


Hi, this is not a rule but most of the non-destructive physical changes are reversible.

In that group of changes you may find:

  • State changes (solidification, evaporation, etc.)
  • Adsortion and desortion
  • Temperature changes
  • Mixtures

Think of a physical change and then try to figure out which process can reverse that.  

Solution 2
Water freezes into ice, and then ice melts.
Water evaporates and then vapors condenses into liquid water again.
What must be done to crude oil for it to be separated ? It must be filtered or chemically altered
Solution 1
It must be filtered using the different boiling points of the compounds mixed in crude oil. Crude oil is just a mixture of carbon compounds, so it needs no chemical alteration.
Solution 2


It must be vaporized is the answer

Calculate the mass of sodium chloride produced when 5.50 moles of sodium reacts in excess chlorine gas
Solution 1
The mass of NaCl produced is calculated  as below

write the reacting equation

that is  2 Na + Cl2 =2 NaCl

by use of mole ratio between Na :NaCl which is 2 :2 t he moles of NaCl is also = 5.50 moles

mass  of NaCl= moles x molar mass

=5.50 moles  x58.5 g/mol = 321.75 grams
Which waves move by replacing one particle with another? A) light waves B) sound waves C) electrostatic waves D) electromagnetic waves
Solution 1
Answer: B) sound waves

 There are 2 classifications of waves according to the media of propagation.

Mechanical Waves – needs a medium, an example is sound waves. Sound waves do not travel through a vacuum. Sound waves move by replacing one particle with another. Particles vibrate and that is why we hear the sounds. Electromagnetic Waves and electrostatic waves are one but the same. They do not require a medium.  – an example is light waves.
Solution 2

i think it is B) because Sound waves move by replacing one particle with another. Sound waves require a medium to propagate, or move. Light and electromagnetic waves do not require a medium. Electrostatic are not a type of wave.

hope this helps

What is the key difference between a liquid and a gas?
Solution 1

Answer :

The key differences between a liquid and the a gas is,

  • Shape and volume :

A liquid has no fixed shape but it has a volume.

A gas has neither a fixed shape nor a volume.

  • Inter-molecular space :

A liquid has more inter-molecular space between the molecules.

A gas has larger inter-molecular space between the molecules as compared to the liquids.

  • Inter-molecular attraction :

A liquid has some Inter-molecular attraction between the molecules because of the low Inter-molecular spacing between the molecules.

A gas has very low or minimum Inter-molecular attraction between the molecules because of the larger Inter-molecular spacing between the molecules.

  • Fluidity :

A liquid flow from the higher to the lower region but a gas flow in all the direction.

Solution 2

Liquids and gases differ from each other in the following ways:

1. Intermolecular forces

2. Motion of particles

3. Direction of flow

4. Compressibility

Further Explanation:

Matter can mainly exist in three physical states. These are solid, liquid and gas.


It is that state of matter that has a definite shape and volume. These have a regular arrangement of its constituent particles. These have the strongest intermolecular forces between their constituent particles and therefore the motion of particles in solid is almost negligible. Table salt, wood, and diamond are some examples of solids.


The state of matter with a definite volume but no particular shape is called liquid. The intermolecular forces in the liquids are weaker than that in solids and therefore the motion of particles in liquids is more as compared to that in solids. Milk, water, and bromine are some examples of liquids.


This state of matter has neither a definite shape nor a definite volume. These have a disordered arrangement of its constituent particles. These have the weakest intermolecular forces between their constituent particles and therefore the motion of particles in a gas is the highest among all states of matter. Nitrogen, hydrogen and carbon dioxide are some examples of gases.

Liquids have a definite volume but gases occupy the volume of the container in which these are kept.

Liquids have stronger intermolecular forces as compared to that of gases so the motion of gas particles is more than that of liquid particles.

Liquids are incompressible whereas gases are highly compressible in nature.

The flow of liquid takes place from higher to lower level while gases can move randomly in all directions.

If the number of particles in a mole is 6.022x1023, what is the total mass of 1.81×1024 particles of nitrogen gas (N2)? A. 42 g B. 4.2 g C. 84 g D. 8.4 g
Solution 1
 the total mass  of 1.81 x10^24  particle  nitrogen  gas  is calculated as follows

find the moles of nitrogen

1 moles = 6.022 x10 ^23  particles
what about 1.81 x10^23 =? moles

= (1.81 x10^ 24)/(6.022 x10^23) = 3 moles

mass = moles x molar mass of nitrogen gas = 14 x2 = 28 g/mol

= 3  moles x28 g/mol = 84 grams

A cube of iron (Cp = 0.450 J/g•°C) with a mass of 55.8 g is heated from 25.0°C to 49.0°C. How much heat is required for this process?
Solution 1
c(p)=0.450 J/g•°C
m= 55.8 g
Δt = t(final)-t(initial)=49.0⁰-25.0⁰ = 24.0⁰C

Q=c(p)*m*Δt = 0.450 J/g•°C *  55.8 g*24.0⁰C ≈ 603 J
Q≈ 603 J
Which element has the weakest attractions for electrons in chemical bond

a 4 kilogram cat is resting on top of a bookshelf that is 3 meters high what is the cats gravitational potential energy relative to the floor if the acceleration due to gravity is 9.8m/s A.7j B. 29j C.12j D.118j
Solution 1
GPE = mgh

Where GPE is gravitational potential energy (J), m is the mass ob the object (kg), g is acceleration due to gravity (m/s²) and h is the height (m)

m = 4 kg
g = 9.8 m/s²
h = 3 m

By substitution,
GPE =  4 kg x 9.8 m/s² x 3 m
        = 117.6 J
        ≈ 118 J

Hence, the answer is D
